01 / ABOUT

AI engineering grounded in backend development.

I’ve been building Python services since 2021: APIs, data processing systems and external integrations. At Genotek, I developed and deployed seven multi-agent systems. At ivi, I introduce AI tools and develop the infrastructure that supports them.

I take projects from requirements and architecture through to deployment and maintenance. I document technical decisions, review code and mentor developers.

Multi-agent systems and RAG

I design agent interactions, data retrieval and LLM integrations for products, with call tracing and execution control.

LangGraph / LangChain / RAG / Langfuse

Backend and integrations

I build APIs, data models and background jobs. I optimise queries and caching, and implement error handling for external integrations.

Python / FastAPI / Django / PostgreSQL

Harness engineering

I build agent execution infrastructure: tools, context management, instructions and task orchestration.

Tools / Context / Instructions / Orchestration

Architecture and operations

I design services and their interactions, set up builds, deployments and CI/CD, and document architectural decisions.

Docker / CI/CD / Redis / System Design
